This work tells the story of a male protagonist who had an accident with his family in his previous life. He traveled to a different world and was reincarnated as a red demon wolf. He grew up step by step, accepted himself bit by bit, and made up for his own regrets bit by bit. There may be some sad situations mentioned later, but I promise I will not hurt you. This is my first time writing a book. I wrote it all during my off-duty hours. If you have any comments, I will try my best to correct them. I hope everyone can be merciful.
